# 7.2. Sound System

Using the sound system panel, you can easily adjust settings to the sound output KDE and its applications produce.

## 7.2.1. Bell

KDE generates various warning signals, called beeps, when you make a mistake (e.g. copying a file into a folder you do not have access to). You can adjust the settings for these beeps here:

Volume

  Sets the volume of the beep. You can set it from 0% (no beep) to 100% (you should think carefully before making a mistake after setting this...)

Pitch

  Adjusts the frequency of the tone. Ranges go from 0 (no beep) up to 2000 (you should not set this unless you have no pets like dogs or bats.)

Duration

  Tells KDE how long the tone is played.
